The Philosophers' Cocoon

In our newest "how can we help you?" thread, D writes:

I recently got a paper accepted for publication, and the editor sent my manuscript to the typesetting office. Since then, I noticed a few typos and minor mistakes that I had somehow missed until now (and so did my reviewers). Since I still have not received the proofs, do you think it is all right to contact the editor and let them know I would like to fix these mistakes? Or is it already too late for that?

A couple of readers submitted responses. An Editor writes:

The time to fix this is in the proofs. When you get your proofs read them with care. There is a chance that some of the mistakes will be caught in the proof stage, by others involved. But if they are not you will get a chance. Further, as an editor of a journal, I read the proofs as well, and catch yet-uncaught errors. But wait for the proofs.

Mike Titelbaum added:

Presumably once the piece is typeset they will send you proofs. Are the typos minor enough that you could fix them in the proof-correction stage?

It seems to me that Mike's question here is potentially important. One should ordinarily not make significant substantive changes to a final manuscript without running them by the Editor, right? But this doesn't sound like what the OP is describing. If it's just a matter of a few typos here and there, that's what proofs are for fixing!
